Yes! This! Let's be reasonable adults about this: node.js and V8 are very new projects that are really impressive given their age. OTP is an incredibly mature and proven platform.

EDIT: If you're interested to really see what node.js's main issues are, check out Ryan Dahl's (node.js creator) presentation at JSConf.eu 2010. http://jsconf.eu/2010/speaker/techniques_for_a_single_stack....

EDIT (2): Yes, meant OTP, not OLTP. :)
